(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) 3 Claims.

without the-payment to me of any royalty there- I hereby dedicate theinvention herein described to the free use of the People in theterritory of the United States to take effect on" the granting of apatent to me.

This invention relates to panel construction, and more particularly tothe construction of the individual panels. 7

One of the objects of this invention is the provision of a panel whichcan be fabricated of small inexpensive pieces of wood.

Another object of this invention is the provision of a panelprefabricated with an insulating backing.

In the accompanying drawing there is illustrated an embodiment of thisinvention, in which:

Figure l is an isometric view of a panel constructed in accordance withthis invention with the back thereof facing upward.

Figure 2 is a rear elevational view, partly in section.

Figure 3 is a section along the line 3-3 of Figure 2.

Figure 4 is a section along the line 4-4 of Figure 2.

Referring with more particularity to the drawing in which like numeralsdesignate like parts, the embodiment illustrated comprises a panelfabricated of a plurality of crosspieces ll connected by means of tongueand groove joints I2. On the back of the connected crosspieces il asheet ll of fabric or building paper, or other suitable material, isdisposed, which is held in place together with the crosspieces II bymeans of two longitudinal cleats l4, it. Each crosspiece is secured tothe cleats by nails l5 disposed flrst through apertures It in the cleatswith the point of the nails embedded in the crosspieces after passingthrough the sheet ii. To prevent strain under atmospheric changes. theapertures it are made slightly larger than the nails I! or are slottedin a longitudinal direction with respect to the panel.

The heads of the nails I! are preferably countersunk in the cleats It soas not to protrude beyond said cleats. If a wider bearing surface isdesired, washers (not shown) may be disposed between the heads of thenails and the cleats. If ui'ies'i-ed, screws may be used instead of thena Between corresponding ends of the cleats l4,

l4 cross cleats l1, I! are secured to the panelforming a boxconstruction within which insulation material I8 of the fill type, suchas sawdust, wood shavings, mineral wool, peat moss, or other vegetableor mineral fiber, is compressel and covered with a sheet IQ of fabric orbuildin paper. The sheet it extends over the sides of the cleats l4, l4and l7, l1 and is secured thereto by means of laths or strips. 20 nailedthrough said'strips and through sheet l9 into the said cleats,substantially as illustrated. If desired,

sheet l9 may be glued to the cleats or secured thereto in any othersuitable manner.

Panels constructed in this manner may be used for either interior orexterior construction. When used for interior construction, the sheet l3should be of a highly moisture resistant type to prevent moisture fromthe interior of the building condensing on the insulation or in theouter wall behind it as it is cooled to the dewpoint by outdoortemperatures. The sheet l9 should be of a non-moisture resisting orporous type to permit breathing of the insulation into the hollow wallspace. For use in exterior construction, such as for exterior walls androofing, the types of materials used for the sheets l3 and I 9 should'bethe reverse of that described for interior use. 1

Having thus described my invention, I claim:

1. A building panel comprising a plurality of crosspieces, longitudinalcleats secured to the backof said crosspieces, cross cleats secured atthe ends of said longitudinal cleats, \all of said.

cleats forming a box, a sheet of material between said cleats and saidcross pieces, insulating material in said box, and a cover sheet oversaid cleats and insulating material.

2. Abuilding panel for interior construction comprising a plurality ofcrosspieces, longitudinal cleats secured to the back of saidcrosspieces, cross cleats secured at the ends of said longitudinalcleats, all of said cleats forming a box, a sheet of moisture resistantmaterial between said cleats. and said crosspieces, insulating materialin said box, and a porous cover sheet over said cleats and insulatingmateriaL.

3. A buflding panel for exterior construction comprising a plurality ofcrosspieces, longitudinal cleats-secured to the back of saidcrosspieces, cross cleats secured at the ends of said longitudinalcleats, all of said cleats forming a box, a sheet of porous materialbetween said cleats and said crosspieces, insulating material in saidbox. and a moisture resistant cover sheet over I said cleats andinsulating material.
